..Left Ventricular Assist Devices (LVAD) are increasingly used as a bridge to transplant (BTT) for patients with advanced congestive heart failure (CHF) and are assigned United Network for Organ Sharing (UNOS) high priority status (1B or 1A)...

Development of a novel echocardiography ramp test for speed optimization and diagnosis of device thrombosis in continuous-flow left ventricular assist devices: the Columbia ramp study

..This review addresses the clinical characteristics, natural history, prognosis and treatment strategies for this group, with special emphasis on the optimal timing for revascularization, and the role of glycoprotein IIb/IIIa inhibitors...

..However, a certain number of patients continue to have significant mitral regurgitation (MR) under LVAD support. We investigated pre-operative echocardiographic features associated with persistent MR after LVAD implantation...

..Neurologic complications (NCs) are the major adverse events after left ventricular assist device (LVAD) surgery. Pre-operative and post-operative factors associated with NCs in patients with LVADs were investigated...

..However, with the newer anti-retroviral drugs, the estimated 10-year survival after seroconversion is exceeds 90%. This case series describes the intermediate range outcome of HIV-positive cardiac transplant recipients...

..7%). One patient (14.3%) experienced a bleeding complication after the procedure. For patients with a high VA burden after LVAD implantation, VT ablation is safe and feasible, but VA frequently recurs. ..

Serial echocardiography using tissue Doppler and speckle tracking imaging to monitor right ventricular failure before and after left ventricular assist device surgery

..The patients eventually underwent cardiac transplant successfully, and the partial clot was found inside of the pump. This case demonstrates the usefulness of serial ramp studies in patients who are suspected to have device thrombosis. ..

Validity and reliability of a novel slow cuff-deflation system for noninvasive blood pressure monitoring in patients with continuous-flow left ventricular assist device

..Current data regarding the physiologic effects of NO and nitric oxide synthase (NOS) inhibitors on the cardiovascular system are reviewed. Clinical trials assessing the safety and efficacy of NOS inhibitors in CS are summarized...

Short and long-term outcome of pregnant women with preexisting dilated cardiomypathy: an NTproBNP and echocardiography-guided study

..However, with improving mechanical circulatory support device (MCSD) technology, the treatment options for RCS patients are expanding. We report on a recent 5-year single-center experience with MCSD for treatment of RCS...

..Cardiac retransplantation is the definitive treatment for allograft failure despite decreased long-term survival in these patients. The cause of the poorer outcomes in cardiac retransplant patients is unclear...

..8 days. All three deaths were due to neurologic complications. MCS should be considered in patients with fulminant myocarditis complicated by shock. With aggressive medical therapy, early utilization of MCS carries promising outcomes...

Acquired von Willebrand disease during CentriMag support is associated with high prevalence of bleeding during support and after transition to heart replacement therapy

Kerry A MorrisonFrom the Division of Cardiology, Columbia University Medical Center, Columbia University College of Physicians and Surgeons, New York, New York and Department of Cardiothoracic Surgery, Columbia University Medical Center, Columbia University College of Physicians and Surgeons, New York, New YorkASAIO J 60:241-2. 2014

..We found that acquired vWD is common early post CentriMag implantation and is associated with frequent bleeding events and high requirement of blood products. ..

A stepwise progression in the treatment of cardiogenic shock

Ari PollackDepartment of Medicine, New York Presbyterian Hospital Columbia University Medical Center, New York, New York, USAHeart Lung 41:500-4. 2012

..We also review the literature with regard to the use of percutaneous left ventricular assist devices in the setting of cardiogenic shock...

Prevalence of de novo aortic insufficiency during long-term support with left ventricular assist devices

..We compared the prevalence of aortic insufficiency (AI) after HeartMate II (HMII) vs HeartMate XVE (HMI) support and assessed the role of aortic root diameter and aortic valve opening in the development of AI...

Utilization of defibrillators and resynchronization therapy at the time of evaluation at a heart failure and cardiac transplantation center

..Previous studies suggested a higher incidence of acute heart failure (AHF) during cold months in regions with cold climate. We examined the daily incidence of AHF by same-day trough temperature and humidity in a warmer region...

..This study aimed at elucidating whether peripheral venous congestion is sufficient to promote changes in inflammatory, neurohormonal, and endothelial phenotype similar to those observed in HF and RF...
